JetTalk: Selecting the right cutting technology for your project
There are various industrial cutting technologies available in the market such as waterjet cutting, laser, plasma and Electrical Discharge Machining (EDM).
Selecting the right cutting technology for your project may depend on a number of variables such as the type and thickness of the material, the level of precision and quality of the cut.
Let’s explore these options including the capabilities and advantages of each technology.
Abrasive Waterjet Cutting
Waterjet cutting is a cold cutting process which uses a combination of garnet abrasives and high-pressure stream of water to cut almost any material such as steel, titanium, stone, wood and glass. The pressure applied during the cutting process can range from 60,000 to 90,000 psi.
Plasma cutting is a thermal process where electrically heated ionised gas – plasma is forced through a small nozzle orifice in the torch; it generates an electric arc cuts through the material by melting it at high temperature of up to 22,000° C (40,000° F).
Laser cutting is also a thermal process where a focussed beam is directed at the material. The material either melts, burns, vaporises or gets blown away by a jet of gas.
Electrical Discharge Machining (EDM)
Also known as spark machining, EDM is a production process which directs high-frequency spark discharges from a graphite or soft metal tool at the material to cut/remove electrically conductive materials such as hardened steel or carbide.
